What It Is and How It Works
Ivermectin is an anti-parasitic medication derived from avermectins, compounds obtained from the fermentation of Streptomyces avermitilis, a type of soil bacteria. It works by binding to invertebrate muscle and nerve cells, leading to increased permeability of the cell membrane, which results in paralysis and death of the parasite. This mechanism is effective against a variety of parasites and is commonly used for conditions such as onchocerciasis (river blindness) and strongyloidiasis.
Additionally, ivermectin works in some skin conditions by exerting an anti-inflammatory effect, which may contribute to its effectiveness in treating inflammatory skin conditions.
Indications / Uses
Ivermectin is primarily used for treating parasitic infections, including:
- Onchocerciasis (river blindness)
- Intestinal strongyloidiasis
- Scabies
- Head lice
- Other parasitic infections as determined by a healthcare provider
Off-label uses of ivermectin have been suggested in various jurisdictions and may include aspects of disease prevention or treatment in certain conditions, yet these uses should only be considered under the strict supervision of a healthcare professional due to varying evidences of efficacy and safety.
